11.6.3 Vertical unit with post-heating coil
As shown in the figu re below, by simply changing the position of two panels it is possible to suck or blow out air from the
sides instead from the front of the unit
Page 23
IOM / MINIAIR-0507 21
11.7 By-pass for de-frosting or free-cooling
For MINIAIR+ 03-06-10-14-19-25-30 models the structure has a presplitting allowing defrosting by-pass or free cooling to
be carried out.
Free cooling. When the external tem perature is close to the internal temperature the recuperator may be bypassed
inserting renewal air directly in the room.
It is possible to do this by opening damper B and at the same time closing damper A.
Defrosting. In very cold periods the room delivery air could frost blocking the passage through the recuperator. Installing
an antifreeze thermostat (optional) combined with the bypass system indicated in the figure unit defrosting is obtained. In
fact opening gate A and closing gate B the recuperator is bypassed with cold air and the flow of hot air coming from the
room air delivery allows a rapid defrosting of the recuperator itself which can therefore return to operation in normal
conditions.
SECTION 12 – TRANSPORTATION
12.1 Packing
The recuperators are placed in carton boxes that must remain intact until the moment of installation.
The materials that are not required for technical motives are supplied in fitted packing fixe d externally and internally to
